ii think it's water
A water hydrant may leak and spew water when a hose is attached due to several factors, including improper sealing of the hose connection, a damaged or worn-out washer or gasket, or a malfunctioning valve inside the hydrant. Additionally, if the hydrant is not fully closed or if there is excessive water pressure, it can exacerbate the leakage. In some cases, debris or sediment can obstruct the valve, preventing it from sealing properly. Regular maintenance can help prevent these issues.
Your question is not definite but is sounds like you are describing a geyser

It can be argued whether or not spew is an onomatopoeia, but most will agree it is not. The definition of spew is to expel large quantities of something forcibly. Spew can be used to describe vomiting and puking. Onomatopoeia is used to describe a word that sounds like what it means. Such as the word buzz.
You shake it!!
